Runli YLL series organic thermal medium boiler is an assembled forced circulation vertical traveling coal-combustion boiler.The heating surface of this series boiler has a compact structure, is composed of inner, middle and outside closepacked round coil, inner coil is the radiation heating surface, the outside surface of outside coil and inner coil forms a convection heating surface.The air preheating device is designed in the rear of boiler.The boiler is made up of the upper proper and the bottom fire grate, will be assembled on the application site.After fuel burns completely in combustion chamber, the radiation heating surface will absorb most of heat quantity, following which, the high temperature fume will enter into convection heating surface for heat exchange.When coming out of boiler, it will heat air necessary for combustion in air preheater, and then will be released into atmosphere through chimney by induced-draft fan through dust catcher.

1. Simple installation and short installation period Just combine the upper body with the lower combustion chamber2. The closely-aligned round coils form the sufficiently arranged heating area to reduce the surface heat load of pipe and handle the heat conduction oil safely3. Reasonable medium flow Heat conduction oil flows from the lower inlet to the upper outlet Gas generated during the operation hardly slays ill the boiler and can exhaust easily4. Adiabatic combustion ill the combustion chamber Fire the fuel more easily and sufficiently, and improve the heating efficiency5. Closely aligned coils are arranged on the boiler lop, which call protect the top better from burnt damage
